Abstract

The boiler using oil, gas or solid fuel has a combustion chamber enclosed by a water jacket (3) with a chimney discharging upwards from the middle of the top of the chamber. The flame (5) is directed horizontally inwards from one side to a flame spreader (1) suspended near the middle, designed to ensure even heating and greater efficiency for heating the water. The interior lining (4) for the chamber can be of cast iron, with steel inserts and firebrick forming heat transfer ribs also having heat storage properties. Alternatively the lining can be of steel. The shape is intended to slow down the speed of flow of the hot gases, and direct the heat over the whole of the interior. The size of the flame can be reduced accordingly.

Description

Beschreibung:Description:

Die Erfindung bezieht sich auf die Ausgestaltung einer Brennkammer für flammenbeheizte Heizkessel für feste, flüssige und gasförmige Brennstoffe.The invention relates to the design of a combustion chamber for flame-heated boilers for solid, liquid and gaseous fuels.

Besagte Heizkessel werden zur Wohnraum-, Industrie- und Landwirtschaftsbeheizung verwendet.Said boilers are used for domestic, industrial and agricultural heating used.

Der Flammenteiler (1) hat die Aufgabe die Wärmeverteilung im Brennraum gleichmäßig zu verteilen.The task of the flame splitter (1) is to distribute heat in the combustion chamber to distribute evenly.

Die Verrippung (2) sowie hervorstehende Behinderungen, die je nach Größe und Beschaffenheit des Brennraumes unterschiedlich sein können, incl. Plammenteiler (1) verhindern, daß die Abluftgase bzw. Heizgase mit zu großer Geschwindigkeit und mit zu hoher Temperatur den Brennraum verlassen.The ribbing (2) as well as protruding obstructions, depending on the The size and nature of the combustion chamber can be different, including the plasma divider (1) prevent the exhaust gases or heating gases from being too high and leave the combustion chamber at too high a temperature.

Desweiteren wird erreicht, daß die Flammenspitze eine punktuelle Überhitzung des Brennraumes verhütet. Die Lebensdauer des Kessels wird dadurch günstig beeinflußt.Furthermore, it is achieved that the flame tip overheating at certain points of the combustion chamber prevented. This has a positive effect on the service life of the boiler.

Die Verrippung (2) die bei einem nachträglichen Einbau des Kessels aus verschiedenen feuerfesten Materialen bestehen kann, sowie auch der Flammenteiler (1) selbst, sind nach meiner Erfahrung am günstigsten in Guß ausgeführt. Bei neu hergestellten Kesseln dürfte die wirtschaftslichste Form in vorgewalzten Profilen oder durch anschweißen von Profilen erreicht werden.The ribs (2) when the boiler is retrofitted can consist of various refractory materials, as well as the flame divider (1) themselves, in my experience, are best made of cast iron. When new Manufactured boilers are likely to be the most economical form in pre-rolled profiles or by welding on profiles.

Bei einem nachträglichen Einbau in vorhandene Kessel muß die Größe der Durchbrüche des-Profils so gewählt sein, daß die Kesselwände (4) Wärme aufnehmen können um sie an das Wasser (3) zu übertragen.When retrofitting in existing boilers, the size the openings of the profile should be selected so that the boiler walls (4) absorb heat can to transfer them to the water (3).

Die nachträglich eingebaute Verrippung (2) selbst hat noch die usätzliche Aufgabe die Wärme zu speichern um sie dann bei Brennerstillstand an die Brennraumwände abzugeben. Zweckmäßig ist es dann,.die Abluftklappe zusätzlich noch so zu steuern, daß sie bei brennerstillstand schließt.The subsequently installed ribs (2) still have the additional ones The task of storing the heat and then transferring it to the combustion chamber walls when the burner is at a standstill submit. It is then advisable to also control the exhaust air flap in such a way that that it closes when the burner is off.

Um nochmals zusätzlich den Ölverbrauch zu verringern, empfiehlt es sich eine kleinere 3renndüse zu verwenden.In order to further reduce the oil consumption, it is recommended to use a smaller 3-race nozzle.

Größe dieser Düse kann nur durch Erfahrungswerte ermittelt werden.The size of this nozzle can only be determined by empirical values.

Ein weiterer Vorteil ist, daß durch diese Wärmespeicherung die Stillstandzeiten des Brenners verlängert werden.Another advantage is that this heat storage reduces downtimes of the burner.

Bezeichnung: Brennkammerausgestaltung eines Heizungskessels Patentansprüche: Brennkammerausgestaltung eines Heizungskessels für Flüssige, feste und gasförmige Brennstoffe 1. Vorliegender Patentanspruchwird dadurch gekennzeichnet, daß die Brennkammerwände durch Verrippun6r hervorstehender Behinderungen ausgekleidet sind. Die Auskleidung kann nachträglich durch dementsprechende Gußteile, gestanzte Stahleinsätze sowie feuerfeste, wärmespeichernde Steine erfolgen Sie kann ebenfalls durch prmfilierte Stahlbleche gebildet werden oder gegossen sein. Designation: Combustion chamber design of a heating boiler Claims: Combustion chamber design of a heating boiler for liquids, solids and gases Fuels 1. The present claim is characterized in that the combustion chamber walls are lined by ribbing protruding obstructions. The lining can be retrofitted with appropriate castings, stamped steel inserts as well Refractory, heat-storing bricks can also be made by prmfilierte Steel sheets are formed or cast. 2. Die Ausbildung des Profils ändert sich nach der Größe des Brennraumes sowie dessen Gestalt. Zweck des Profils ist es, eine große Oberfläche zu bilden, wärmespeichernd zu wirken sowie die Geschwindigkeit der Rauch- und VerbrennungsKase stark zu verlangsamen um deren Austrittstemperatur zu senken um somit den Wirkungsgrad des Kessels zu erhöhen. 2. The formation of the profile changes according to the size of the combustion chamber as well as its shape. The purpose of the profile is to create a large surface, to have a heat-storing effect as well as the speed of the smoke and combustion cheese to slow down strongly in order to lower their outlet temperature and thus the efficiency to increase the boiler. Dadurch bedingt kann der Düsenquerschnitt des o1-oder Gasbrenners verkleinert werden. As a result, the nozzle cross-section of the oil or gas burner can be reduced in size. 3. Die Profilveränderung kann nachträglich an aie Brennwände des vorhandenen Kessels durch schweißen, verstiften, verkeilen oder aufeinanderlegen der Profile angebracht werden. 3. The profile change can subsequently be applied to the firing walls of the existing boiler by welding, pinning, wedging or laying on top of one another of the profiles are attached. 4. Zusätzlich wird ein sogenannter Flammenspalter in die Brennflamme eingebracht um ein gleichmäßigeres Verteilen der Wärme auf alle Flächen des Brennraumes zu bewirken. 4. In addition, a so-called flame splitter is inserted into the flame introduced to distribute the heat more evenly to all surfaces of the combustion chamber to effect.
